I am very confident that Satoshi Nakamoto is from Europe and not from USA or America or from Asia.
Let me explain how i come to this conclusion. This idea came when i see the time of the first genesis Block. It was established at 18:15:05 GMT.
I am very sure that Satoshi first runs his miner gpu from his apartment. The next logical step is to do this in his personal afternoon relaxing time.
The second evidence is the time that have post in this forum.
If you see this statics

the time that he has done most of his posts was between 15:00 to 23:00 GMT time. He has near zero posts in the morning job europe zone time from 7 to 12.
I have not search if this few posts that has done from 6:00 7:00 or 9:00 GMT time is from one general day or in that day there is a national holiday in a europe country.
The most popular time that he has done some posts here is 17:00 GMT and that means

19:00 Athens Greece
20:00 Moscow Russia
18:00 Vienna Austria
18:00 Rome Italy
18:00 Berlin Germany
18:00 Paris France
